All About ARES

ARES Advantages

Environmental Stewardship and Sustainability
ARES produces no emissions; uses no fossil fuel; does not require water; creates no hazardous waste; requires no harmful extraction of materials; and can be cleanly decommissioned with no lasting impacts.
ARES energy storage facilities are scalable from a 10MW ancillary services installation up to a 2-3GW regional energy storage system.
Extensive Site Options
ARES sites are abundant in arid regions coincident  with wind and solar resources — maximizing transmission resources by providing  storage at the point of intermittent generation.
Constant Efficiency
An ARES system operates at a constant high efficiency over its full range of power output regardless of  discharge state.

Lower Capital Cost
ARES’ cost is approximately 60% of an equivalent power pumped - hydro facility.

Lower Operating Cost
ARES has the lowest annualized capacity cost per kW of comparable technologies.

Storage Energy, with Special Reference to Renewable Energy Sources

"We believe that ARES is an integral part of state and national energy policy, not only in the US, but around the globe, because increasingly, we believe that nations will make a renewed commitment to very high levels of renewable power. ARES gives us a tool that system planners and engineers can put in their tool kit to enable those high levels of renewables while maintaining the reliability and safety of the grid."
